IMPROVEMENT IN WATER-WELS.

The'Schedule referred to in these Lettera Patent and making part of the same.

Tol all whom it 'ma/y concern:

Be it known that I, WILLIAM H. SNYDER, of Phelps, in the county of Ontario, and State O'f New York, havev invented a new and useful Improvement in Water-Wheels; and I do hereby declare that the following is a full, clear, andexact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part Oi this specication, in which- Figure 1 is' a side view of my invention, partly in section, as indicated by the4 line z'x, fig. 2.

Figure 2 is a longitudinal section of the same, taken in the line y y, iig. 1.

Similar letters of reference indicate like parts.

This invention relates to a new and improved waterwheel, of that class which is placed on a vertical shaft, and fitted within a scroll, and are commonly termed turbine wheels.

' The invention consists iu a peculiar construction of rims a a, placed one above the other, and having the bucketsF secured between them.

These buckets are constructed in a peculiar manner, bbeing their face sides, and c the rear sides.

The face sides b are curved slightly at their outer ends, as shown in iig. 2, and the rear sides c are planes, having an oblique position relatively with the face sides b, so that a plane surface, d, is formed or allowed at the Outer end of each bucket, said surfac'es d extending inward from the outer ends of the face sides'b.`

The face and rear sides b c, and also the outer ends d, are all cast or made in one piece, and perfect chutes or'gnides are obtained for the water from the scroll through the wheel, there being the least p0ssible ,ob struct-ion, and consequently a large percentage of the effective force of the water is obtained` The base of this triangular gate, or Outer part, forming the periphery, has a projection, or lip, the Object of which is to arrest the current in the Hume, and

thus receiving the impact thereof, divert it into the gate.

Having thus` described my invention, v I claim as new, and desire to secure by Letters Patenty The hollow bucket F, of triangular form, the base whereof is in excess, so as to form an external lip, or point on the periphery, all substantially as described.

' WM. H. SNYDER.
